Research on Obstacle Classification Using Voyage Bridge Image - towards River Traffic -

航海環境画像を用いた障害物分類に関する研究 -河川交通に向けて-

The aim of this paper as a pre-stage to develop a system that can reduce the burden of ship operators classify obstacles from voyage environment images using neural network and HOG (Histogram of Oriented Gradient). Make a comparison and study with results of the obstacle classification by deep learning. The authors propose the obstacle classification method using the time series information, carry out the evaluation and study to classify obstacles from a river navigation video. The results are summarized as follows: (1) It was automatic classification for voyage bridge images into nine categories. (2) The authors conducted image classification experiments on captured images from a ship. The authors were obtained good correct answer rate and specific rate in the case of using HOG and neural network. (3) The authors conducted obstacle classification experiments using a river navigation video. The authors were obtained the correct answer rate of about 50 percent. (4) When the case of using time series information was obtained a good correct answer rate than not using time series information.
